I have 32 gb of RAM, but whenever i closed or opened new tabs firefox started to take up to 24 gb (out of all available) and then crash, also tabs that normally take milliseconds to load taken more than 10 seconds, uninstalling this extension resolved the problem. It strange that this extension would need so much RAM even if it's collecting your data when it's inactive, and it's certainly shouldn't impact anything when you don't activate it.

It worked fine when I just instaled it. Then it started working with some weird delays or not working at all.
More importantly - I just discovered it'd been the reason my firefox kept crashing, even if I wasn't using it. Very suspicious.

This addon doesn't work, doesn't connect.
This add-on can:Store unlimited amount of client-side data, Access your data for all websites
\\76.0.1

Working good until now...Been using for 1.5 yrs.Now its not working...shows connected but website url stuck on reloading sign.

Firefox is slow............remove this expansion has been resolved.

This is free because they log everyones data. VPNs that log data would be forced to give up to the authorities should they warrant it.

3.1.5 not work, in FF 75.0

Прокси-сервер отказывается принимать соединения

Firefox настроен на использование прокси-сервера, который отказывает в соединении.

RUBBISH!!! Since Firefox 75.0 I keep getting a box appear asking me for a username and password for authentication!!
UPDATE YOUR APP OR GET RID MORONS!!!

The CPU usage up to 50% when i enable the addon.

System Details: Arch Linux x86_64

Firefox 74.0b3 (64-bit) from mozilla.org

Issue
Right after installing this extension, my system's memory usage went from 800 MiB to 3.7 GiB and then consuming all the available zram and ultimately freezing my whole system! This VPN was good, but developers wrote this very very poorly.

Tip: Don't work for money, your apps will be horrible ;)
